Mowing Your Lawn

Tips for a healthier, greener lawn

A lawn which is properly mowed will be more healthy and better able to resist weeds, disease, and insects.

It is very important to keep mower blades sharp. This may mean blade sharpening several times per season. A dull blade tears the leaves, which not only causes discolouration, but also makes the lawn more susceptible to insects and disease. A common mistake is to mow too short. Short lawns are less tolerant to stress and more prone to disease and weeds. A Kentucky Bluegrass lawn should be mowed to a height of no less than 5 to 6 centimetres, (2-3″). During hot weather increase the mowing height to 8 to 9 centimetres, (3-4″). To ensure the right mower height, measure the mower blade height by placing it on a driveway or sidewalk.

When the grass becomes one third taller than the desired height, it must be mowed. If a mowing is missed, cut halfway back to the intended height, then mow to the normal height several days later. Remove clippings only if they clump or in conditions where there is excessive thatch; otherwise, recycle them back into the lawn. Removing clippings can increase fertilizer requirements by 20 to 30 percent. Avoid mowing your lawn when it’s wet. Vary your mowing pattern to lessen wheel rutting and soil compaction.
